We use an iterative code developed by Van Ballegooijen and
Hussain to compute steady state solutions of the
hydrodynamic equations for a one-dimensional coronal loop
model with asymmetric footpoint heating. We vary the loop
length and heating scale height to construct a
two-dimensional parameter space similar to that of
Aschwanden et al. (2001). This parameter space contains a
boundary that divides a regime where steady state solutions
exist from the regime where there are no steady state
solutions. In this poster we vary the heating scale height
and explore the onset of instability using a
state-of-the-art adaptive mesh code called FLASH to solve
the time-dependent hydrodynamic equations for the
one-dimensional coronal loop model with asymmetric footpoint
heating.
